Histological examination of tissues of experimental fish

Abstract

Nutrition and pathology are related disciplines.
Gounelle (1961) observed that "Every disease has a nutritional
aspect. Pathology is concerned with specific disease
process and resultant tissue changes in the individual what
ever its systemic position. The study of disease process
involves at a greater extent the histological examination of
various organs and tissues. The histological examination of
tissue in a nutritional experiment provide an opportunity to
observe the resultant changes occurring at cellular level.
Many times a particular treatment may not produce any
physiological or reproductive effect immediately; however
histological examination may reveal considerable changes.
It is also important before advocating any feed or a
combination of feed for field use we have to ascertain
whether the said combination contain any type of toxic factor
This can be settled only by conducting an experiment in which
histopathological examination forms the major component.
